Kerastase Elixir Ultime Review

What We're Sweet On: The Elixir of Life . . . For Your Hair

What's the first thing you think of when you hear "hair oil"? If you're thinking argan, you're in the majority — it seems as if lately this amber oil has dominated the hair oil discussion. But argan isn't always enough, and Kérastase's Elixir Ultime ($54) is here to prove that. A potent cocktail of four different oils, this hair serum can be used in a slew of ways: as a preshampoo treatment, a leave-in conditioner, for postblow-dry smoothing, or for a serious dose of shine.

The secret? The four fabulous oils, of course. Maize oil delivers on the shine, while pracaxi oil deep-conditions your strands. Camellia oil smooths out the hair fiber and our old friend argan acts as a barrier to protect hair from external aggressors. A four-in-one treatment that takes care of all of our beauty woes? We're thinking 2013 will be the year of flawless hair.
